Long anticipated, Yahoo finally released its desktop search application a few moments ago. Overall, I'm impressed with the product, even though it's little more than a Yahoo-skinned version of the X1 desktop search tool, at least at this point.
Upsides: Powerful search capability, supporting more than 200 file formats. Excellent filtering capability, allowing you to quickly pinpoint desired files. And a killer preview function which displays documents and even queues up multimedia files in Windows media player.
Downsides: Virtually no web search integration, and no indexing or caching of web pages viewed—one of Google Desktop's strongest features. But Yahoo calls this a "living beta" and says that will change soon. Read on for more in today's SearchDay article, Yahoo Launches Desktop Search.
